this may have been asked and answered before . . . if so my apologies.

When I set up new XP installations, I always do windows update right off the bat and install all security patches etc. It's usually not an issue since I have broadband and it only takes a few minutes. But I may not always have broadband at my disposal. Where can I get the critical updates as .exe files to burn to a cd to use if I don't have broadband available when setting up a new XP install?
